IMPROVEMENT lN CANE-COVERER S.

Specification forming part of Letters Patent No. 27,339, dated March 6, 1860.

To all whom it may concern:

Be it known that I, JOHN ALLISON, of St. Martinsville, in the parish of St. Martin and State of Louisiana, have invented a new and Improved Machine for Uovering Cane; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making a part of this specification, in which Figure 1 is a longitudinal vertical and central section of my invention; Fig.2, a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a machine for covering cane that will during the operation pulverize the earth and cause the seed 'to be covered with a loose, light, and pli ablemold, permeable to air and moisture, thereby greatly favoring its germination.

The invention relates to an improvement on a machine for covering cane for which Letters Patent bearing date November 24, 1857, were granted to me; and it consists in a peculiar arrangement and combination of blades or shares, rotary barrows, a stationary harrow, and a roller provided with a scraper and fitted with one or more rotary harrowsin a swinging frame, whereby the desired end is attained.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

AAare two pieces of boards or planks,which are secured at a proper distance apart by traverse-bars, a a, said boards or planks having an oblique position relatively with each other, so that the space B between their back ends will be narrower than the space 0 between their front ends, as shown clearly in Fig. 2. To the lower edge of each board or plank Aan iron or steel blade, I), is attached. These blades have a slight inclination downward and inward toward each other, as will be understood by referring to Fig. 2.

E is a frame, which is attached to the back parts of the boards or planks A A by bolts a a, the frame being allowed to swing freely on said bolts. In the back part of the frameE a concave roller, F,is placed, and a scraper, G, is secured in the back part of the frame, said scraper being behind the roller F, as shown more particularly in Fig. 1. In the frame E, and directly in front of the roller F, two rotary harrows, H I, are placed, one in front of the other, the front harrow, H, being rather more elevated than the back one, I, for the reason hereinafter stated.

Between the two boards or planks A A a rotary harrow, J, is placed, said harrow being parallel with the traverse-bars a a, as shown clearlyin Fig. 2, and somewhat above the blades or shares 1), as shown clearly in Fig. 1.

To the front parts of the boards or planks A A a V-shaped harrow, K, is attached. This harrow'is formed by having suitable teeth, 0, in a bar, 0, the inner parts of which are attached by pivots d one to each board or plank A, and the ends terminating in slotted arms 0, through which set-screws f pass into the boards or planks. The harrow K may be adjusted higher or lower by regulating the screws f. The slotted arms 0 are clearly shown by the dotted lines in Fig. 1.

To the front traverse-bar a of the boards or planks A A a draft-chain, L, is attached, and handles M M are secured to the bars a (t.

The boards or planks A A, blades or shares D D, frame E, roller F, and scraper Gr were used in the patented machine previously referred to; but the rotary harrow's H I J, arranged as shown, and the stationary adjustable harrow K are new.

The operation is as follows: The team is hitched to the machine, which is placed directly over the row of cane or seed to be covered. As the implement moves along the dirt is scraped up by the blades D, accumulated, and raised by the boards A and through the opening B. The rotary harrow J, which is operated only by the resistance ofiered to itby the earth during the movement of the implement, pulverizes the earth, so that it will fall into the furrow in which the seed is planted and cover the same. The rotary harrows H I still further pulverize the earth after the seed is covered, the harrow H breaking the larger lumps or clods of earth and the lowermost harrow, I, breaking the small lumps. The roller F compresses the earth on the seed and leaves a convex ridge. The scraper Gr, preventing earth adhering to the roller F, and the front stationary adjustable harrow, K, break all clods of earth and prepare it properly to receivethe The boards or planksA A,with bladesD D, action of theblades or sharesDDand harrow J. rotary barrow J, and adjustable barrow K at- The swinging frameE admits of the rollerP tached, the frame E, provided with the roller and barrows H I conforming to the inequalities F, scraper G, and one or more rotary harrows, 0f the surface of the ground. H I, the whole being combined and arranged I do not claim the boards or planks AA with for-joint operation, as and for the purpose set blades D D attached, nor the roller-frame E 'forth.
